Rename all references of sparcv9 to sparc64, to make Zig align more with
other projects. Also, added new function to convert glibc arch name to Zig
arch name, since it refers to the architecture as sparcv9.
This is based on the suggestion by @kubkon in PR 11847.
(https://github.com/ziglang/zig/pull/11487#pullrequestreview-963761757)
* Added peer type resolution for arrays and vectors: the vector type is
selected.
* Fixed passing the lhs type or rhs type instead of the peer resolved
type when calling Value methods during analyzeArithmetic handling of
comptime expressions.
* `checkVectorizableBinaryOperands` now allows mixing vectors and
arrays, as long as one of the operands is a vector.
This matches stage1's handling of `^=` but apparently stage1 is
inconsistent and does not handle e.g. `*=`. stage2 now will always allow
mixing vector and array operands for all operations.
* Use `@Vector` syntax instead of `std.meta.Vector`.
* Use `var` instead of `const` for tests so that we get runtime
coverage instead of only comptime coverage. Comptime coverage is done
with `comptime doTheTest()` calls.
Notably, Value.eql and Value.hash are improved to treat NaN as equal to
itself, so that Type/Value can be hash map keys. Likewise float hashing
normalizes the float value before computing the hash.
* Sema: fix `zirTypeInfo` allocating with the wrong arenas for some
stuff.
* LLVM: split `airDbgInline` into two functions, one for each AIR tag.
- remove the redundant copy to type_map_arena. This is the first
thing that lowerDebugType does so this hack was probably just
accidentally avoiding UB (which is still present prior to this
commit).
- don't store an inline fn inst into the di_map for the generic
decl.
- use a dummy function type for the debug info to avoid whatever UB
is happening.
- we are now ignoring the function type passed in with the
dbg_inline_begin and dbg_inline_end.
* behavior tests: prepare the vector tests to be enabled one at a time.
Mitigates #11199.
This was an attempt to move saturating_arithmetic.zig to the "passing
for stage2" section, which did not pan out due to the discovery of 2
prerequisite items that need to be done, but I did make a bug fix along
the way of the calculation of max/min integers.
This commit also simplifies the saturating arithmetic behavior tests to
depend on less of the zig language that is not related to saturating
arithmetic.

Master branch added `try` to a bunch of testing function calls, and some
lines also had changed how to refer to the native architecture and other
`@import("builtin")` stuff.
